    Since I am driving a greenwheel GTX, I would say try a 14/19, I don't think a greenwheel by itself can pull a 15/20.

    You might like the 15/20r cause i have the 14/19r and am running it very well with just the free mods and the 4'' intake, and free flow exhaust, i keep going 8120 rpms all day even in the heat. Hoping this week to be ordering the green wheel though and maybe a green hulk water box.

    Father in law has the same setup you are considering with the the following exception--no wedge and has a freeflow exhaust. I set him up with a Solas 14/19 pitched to 14/17. Runs 8200 in the cooler weather and 8000 + in the hot weather. He is around 250 lbs. That was a perfect prop for his particular ski.

    Is it a 14/19 with 2mm taken out or was it repitched by Impros or others to a 14/17?

    It was a 14/19 Solas that that I was initially using in my stage 3 Rxp and had Glen @ Skat Trak take it down to a 14/17 for my father in law to use after adding the sc'r.
